MESSAGE-RECORDING INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 426,555, dated April 29, 1890. Application filed October 29,1889- Serial No. 328,548. (No model.)

To all whom it may concern:

Be it known .that I, JOHN C. WVILSON, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Message-Recording Instruments, of which the following, with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention is intended as an improvement upon the message-recording instrument shown and described in application, Serial No. 278,170, filed June 25, 1888, and has particular reference to the inking mechanism.

In accordance with this invention an inking-roller normally bears on the markingroller. The inking-roller is journaled in or pivoted to an arm or frame, which in turn is loosely connected bya link to a rock-shaft or bar which has its bearings in the side frames of the instrument, thus supporting the inking-roller on a rock-shaft by means of a toggle-jointed arm or lever. An operating-lever or finger-piece is secured to the rockshaft outside the said frame, by means of which the said shaft is rocked and the inking-roller moved. An ink reservoir or tank is placed in suitable position near the marking-roller, and a small roller is contained in said tank, revolving in the ink contained therein. A conveying-roller is journaled in the frame-work, bearing on the roller contained in the ink-reservoir, and a thumb-nut is secured to the shaft of said conveyingroller, by which it may be revolved manually when desired. The conveying-roller is arranged adjacent to the inking-roller, so that the latter maybe moved by the rock-shaft into contact therewith to be inked when desired.

My invention therefore consists in details of construction to be hereinafter pointed out.

Figure 1 shows in side elevation a longitudinal section of a message-recording instrument embodying this invention Fig. 2, a plan view of a portion of the register to be referred to; and Fig. 3, a side View of a portion of the register, showing portions of the operatingparts herein to be described.

The main frame-work of the register comprises a base-plate and suitable side and top plates.

The paper-feeding mechanism and motor mechanism for moving it, the recordingpen,

and recording-pen magnets are all substantially the same as in the specification above referred to.

The marking-roller c is arranged on a shaft 0 directly above the recording-pen e. An inking-rollerfis journaled in or pivoted to an arm a, loosely connected to a short arm or link a, fixed to a rock-shaft 0. The arms a a, connected as shown, constitute a togglejointed arm or lever supporting or bearing the inking-roller f. An operating-lever or finger-piece b is secured to the rock-shaft a by means of which it is rocked. The inkingroller f normally bears on the marking-roller. An ink-reservoir c is held in suitable position near the inking-roller f, and a roller 0 is contained in said reservoir, revolving in the ink contained therein. A conveying-rollerf is j ournaled in the frame-work normally bearing on the roller 0 and a thumb-nut f is secured to the shaft on said conveyingroller f and accessible outside the main frame-work, by means of which said conveying-roller may be revolved manually when desired.

The parts being arranged as thus described, when it is desired to supply the ink-roller f with ink, the operatinglever b is depressed, rocking the shaft a and throwing the said inking-roller f into contact with the conveying-roller f, and while held in such position the latter is revolved manually. After the inking-roller f has been sufficiently supplied with ink rotation of the conveying-rollerf ceases, and the operating bar or frame b is released, permitting the said roller f to move away from or out of contactwith the conveying-roller f The printing mechanism thus described is very efficient, and by it the supply of ink may be well regulated at any and all times.

I claim 1. In a message-recording instrument, an ink-reservoir, a roller contained in it, and a manually-revoluble conveying-roller bearing thereon, combined with a marking-roller and an ink-roller bearing on it and movable into and out of contact with the manually-revoluble conveying-roller, substantially as de scribed.

2. In a message-recording instrument, an ink-reservoir, a roller contained in it, and a manually=revo1uble conveying-roller bearing thereon, combined with a marking-roller and an inking-ro11er bearing thereon, a frame supporting said inking-roller, and a rock-shaft supporting the frame, movement of which throws the inking-roller into and out of contact with the said conveying-roller, substantially as described.

3. In a message-recording instrument, an ink-reservoir and roller contained in it, aconveying-rollerbearing on said roller contained in the reservoir, the thumb-nut for rotating it, combined with a marl'cing-roller, an inkroller bearingon it, a rock-shaft and means for rocking it, and a toggle-jointed arm or frame supporting the inking-roller and moved by said rock-shaft, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JNO. 0. WILSON.
